Description

Technical Field

[0001] The utility model relates to the field of angle adjustment, in particular to a low-angle adjustment mechanism of a pan / tilt tripod. Background Art

[0002] A tripod is a stand used to support equipment such as cameras or telescopes. It consists of three parallel legs. This design can provide stable support, making photography or observation more accurate and convenient.

[0003] In the prior art, when adjusting the angle of the supporting legs of the tripod with the angle adjustment function, the angle of the supporting legs can only be adjusted by pressing the limiting members uniformly, which is a rather troublesome operation. Utility Model Content

[0004] The utility model aims to solve the shortcomings in the prior art and proposes a low-angle adjustment mechanism for a pan / tilt tripod.

[0005] In order to achieve the above purpose, the technical solution adopted by the utility model is: a low-angle adjustment mechanism of a pan / tilt tripod, comprising a ball bowl, a surface of which is hinged with a plurality of upper insert racks;

[0006] A mounting groove is provided on the surface of each upper inserting rack, a pressing piece is vertically slidably connected inside the mounting groove, and a first elastic piece is provided at the bottom of the pressing piece;

[0007] The pressing member comprises a first pressing block and a clamping block, and the first pressing block and the clamping block are fixed by a fixing mechanism;

[0008] The bottom surface of the ball bowl is provided with a tooth block adapted to the clamping block;

[0009] A second pressing block is slidably connected in the installation groove, a second elastic member is fixed between the second pressing block and the inner wall of the installation groove, and the second pressing block and the first pressing block are limited by a limiting mechanism;

[0010] Specifically, in the prior art, when adjusting the angle of the supporting legs of the tripod with the angle adjustment function, the angle of the supporting legs can only be adjusted by pressing the limiter uniformly, which is a relatively troublesome operation;

[0011] When the angle of the supporting leg needs to be adjusted, the first pressing block is first pressed to move the first pressing block downward, and the clamping block is driven to move downward synchronously, so that the clamping block is disengaged from the tooth block, and the limit on the upper plug-in frame is cancelled. Moreover, after the first pressing block is lowered, the second pressing block can limit the first pressing block through the limit mechanism, and the first pressing block is restricted from resetting, so that the limit on the upper plug-in frame can be continuously cancelled, and there is no need for manual long-term pressing, which is conducive to adjusting the angle of the supporting leg.

[0012] When the angle adjustment of the supporting leg is completed, the second pressing block is pressed inward to cancel the limit of the first pressing block by the limit mechanism. Under the elastic force of the first elastic member, the first pressing block moves upward and resets, and simultaneously drives the clamping block to move upward, contact with the tooth block, and cooperate with the tooth block to reposition the upper bracket.

[0013] Preferably, the fixing mechanism comprises a latch tongue and a screw, wherein the latch tongue is fixed on the clamping block, and a screw is fixed on the latch tongue, and the screw is used to fix the latch tongue to the first pressing block.

[0014] Preferably, the first elastic member and the second elastic member are both springs;

[0015] Specifically, the first elastic member provides an elastic support force to the first pressing member, so that after the first pressing member stops being pressed downward, the first pressing member can automatically move upward and reset under the elastic action of the first elastic member;

[0016] The second elastic member provides an elastic supporting force to the second pressing member, so that the second pressing member can always have a tendency to move toward the outside of the installation groove.

[0017] Preferably, the limiting mechanism comprises an undercut and a slot provided on the surface of the second pressing block, the undercut is fixed to the back of the first pressing block, and when the first pressing block moves downward, the undercut is inserted into the slot;

[0018] Specifically, when the first pressing block moves downward under manual action, the undercut can move to the position of the slot. Pushed by the elastic force of the second elastic member, the second pressing block pops outward, allowing the undercut to enter the slot. The first pressing block is limited by the engagement between the slot and the undercut.

[0019] Preferably, each upper rack is fixed with a supporting leg at the bottom.

[0020] Compared with the prior art, the utility model has the following beneficial effects:

[0021] When the angle of the supporting leg needs to be adjusted, the utility model first presses the first pressing block to make the first pressing block move downward, and drives the clamping block to move downward synchronously, so that the clamping block is disengaged from the tooth block, and the limit on the upper plug-in rack is cancelled. Moreover, after the first pressing block is lowered, the second pressing block can limit the first pressing block through the limiting mechanism, restricting the first pressing block from resetting, thereby continuously canceling the limit on the upper plug-in rack, and no manual long-term pressing is required, which is beneficial to adjusting the angle of the supporting leg.

DETAILED DESCRIPTION

[0027] The following description is used to disclose the present invention so that those skilled in the art can implement the present invention. The preferred embodiments described below are only examples, and those skilled in the art may think of other obvious variations.

[0028] like Figures 1 to 4 The low-angle adjustment mechanism of a pan / tilt tripod shown in the figure comprises a ball bowl 1, and a plurality of upper inserting frames 2 are hingedly connected to the surface of the ball bowl 1;

[0029] A mounting groove 3 is provided on the surface of each upper inserting frame 2, a pressing piece is vertically slidably connected inside the mounting groove 3, and a first elastic piece 8 is provided at the bottom of the pressing piece;

[0030] The pressing member includes a first pressing block 4 and a clamping block 5, and the first pressing block 4 and the clamping block 5 are fixed by a fixing mechanism;

[0031] The bottom surface of the ball bowl 1 is provided with a tooth block 6 adapted to the clamping block 5;

[0032] It should be noted that there are multiple tooth blocks 6. During production, the number of tooth blocks 6 can be adaptively adjusted according to the number of angle values ​​that need to be adjusted;

[0033] A second pressing block 7 is slidably connected in the installation groove 3, a second elastic member 9 is fixed between the second pressing block 7 and the inner wall of the installation groove 3, and the second pressing block 7 and the first pressing block 4 are limited by a limiting mechanism;

[0034] Specifically, in the prior art tripod with angle adjustment function, when adjusting the angle of the support leg 14, most of them need to press the limiter uniformly to adjust the angle of the support leg 14, which is relatively troublesome to operate;

[0035] When the angle of the support leg 14 needs to be adjusted, the first pressing block 4 is first pressed to move the first pressing block 4 downward, and the clamping block 5 is driven to move downward synchronously, so that the clamping block 5 is disengaged from the tooth block 6, and the limit on the upper plug-in frame 2 is cancelled. Moreover, after the first pressing block 4 is lowered, the second pressing block 7 can limit the first pressing block 4 through the limiting mechanism, and the first pressing block 4 is restricted from resetting, so that the limit on the upper plug-in frame 2 can be continuously cancelled, and there is no need for manual long-term pressing, which is conducive to adjusting the angle of the support leg 14;

[0036] According to the prior art, after the tripod is installed in the middle position or the ground position, when adjusting the height of the tripod, the angle between the support leg 14 and the bowl 1 cannot be limited. Therefore, the tripod with the function of limiting the angle between the support leg 14 and the bowl 1 is difficult to adapt to the existing ground position and the middle position.

[0037] In this embodiment, after the first pressing block 4 is limited, the support leg 14 and the bowl 1 are in a non-restricted state, so that the tripod can be adapted to be placed in the middle or on the ground;

[0038] When the angle adjustment of the support leg 14 is completed, the second pressing block 7 is pressed inwardly to cancel the limit of the first pressing block 4 by the limit mechanism. Under the elastic force of the first elastic member 8, the first pressing block 4 moves upward and resets, and simultaneously drives the clamping block 5 to move upward, contact with the tooth block 6, and cooperate with the tooth block 6 to reposition the upper rack 2;

[0039] Since the ground placement can only be applied to flat ground, when the tripod is used on a bottom surface with complex terrain, the angle positioning of the support leg 14 can be completed by the clamping block 5 and the multiple tooth blocks 6, thereby ensuring the stability of the tripod. After removing the restrictions of the ground placement or the center placement, the angle between the support leg and the bowl can be set larger, thereby lowering the bowl.

[0040] It can be seen that compared with the existing tripod, the device can be adapted to the ground position and the center position, and can also be used alone. It has a wider range of applications, a fast adjustment speed, a wider adjustment range, and is highly portable.

[0041] As a further implementation scheme of the utility model, the fixing mechanism includes a tongue 10 and a screw 11. The tongue 10 is fixed on the clamping block 5. The screw 11 is fixed on the tongue 10. The screw 11 is used to fix the tongue 10 to the first pressing block 4.

[0042] As a further embodiment of the present utility model, the first elastic member 8 and the second elastic member 9 are both springs;

[0043] Specifically, the first elastic member 8 provides an elastic support force to the first pressing member, so that after the first pressing member stops being pressed downward, the first pressing member can automatically move upward and reset under the elastic action of the first elastic member 8;

[0044] The second elastic member 9 provides an elastic supporting force to the second pressing member, so that the second pressing member always has a tendency to move toward the outside of the installation groove 3 .

[0045] As a further implementation scheme of the utility model, the limiting mechanism includes an undercut 12 and a slot 13 provided on the surface of the second pressing block 7, the undercut 12 is fixed to the back of the first pressing block 4, and when the first pressing block 4 moves downward, the undercut 12 is inserted into the slot 13;

[0046] Specifically, when the first pressing block 4 moves downward under manual action, the undercut 12 can move to the position of the slot 13. Under the push of the elastic force of the second elastic member 9, the second pressing block 7 pops outward, so that the undercut 12 enters the slot 13. The first pressing block 4 is limited by the snap-fitting connection between the slot 13 and the undercut 12.

[0047] As a further embodiment of the present invention, a support leg 14 is fixed to the bottom of each upper rack 2 .

[0048] The above shows and describes the basic principle, main features and advantages of the utility model. Those skilled in the art should understand that the utility model is not limited by the above embodiments, and the above embodiments and descriptions only describe the principles of the utility model. The utility model may be subject to various changes and improvements without departing from the spirit and scope of the utility model, and these changes and improvements fall within the scope of the utility model to be protected.
